KDE Community Ships Second Release Candidate of KDE 4.3 Free Desktop, Containing Many New Features and Improvements
July 9th, 2009. The KDE Community today announced the immediate availability of KDE 4.3 RC2, a release candidate of the 3rd iteration over the KDE 4 desktop, applications and development platform.
KDE 4.3 focuses on polishing and completing the user experience by providing a modern and beautiful Free working environment.
This release candidate only contains very few changes compared to the first RC. Please make sure you report any existing issues, and in case of showstopper bugs, contact the KDE release team.
Highlights of KDE 4.3 are...
Integration of many new technologies, such as PolicyKit and Geolocation services
New Window animation effects, a more usable Run Command popup and many new and improved addons in Plasma
Many bugfixes and improvements across all applications and more integration of features coming with the KDE 4 platform
Please note that KDE 4.3 RC2 is not suitable for end users. Its sole purpose is gathering feedback and testing. Following that, we recommend those that are merely out for an upgrade but cannot live with severe instabilities to wait until KDE 4.3.0 is released in late July.
